Re: Erm... What is Brackish water? There really is no correct formula for brackish water since scientifically, brackish water is considered everything between 5ppt salinity (fresh water) to 32ppt (average oceanic salinities). Because most brackish water natural habitats are tidal (the salinity is never stable) it is recommended to start with a baseline salinity of about 22ppt and gradually increase it 2ppt every day for six days, then do a half tank water change at the end of the week and bring the tank back down to 22ppt. Whether this works in practice or not, I don't know. The only "brackish" tanks I've ever keep have been local water ones where I've gotten the water and critters from the estuary itself (aka the Chessapeak Bay).
